Technical Field

[0001] This invention relates to the field of automatic welding machine technology, specifically to a multifunctional automatic welding machine and its usage method. Background Technology

[0002] In modern manufacturing, automatic welding machines are widely used as core equipment in fields such as hardware processing, automobile manufacturing, and aerospace. With the increasing complexity and diversification of product structures, the market is placing higher demands on the functionality, flexibility, and welding quality of automatic welding machines.

[0003] Reference patent (Publication No.: CN222806348U; Publication Date: 2025-04-29) discloses a welding device, relating to the field of electronic component welding technology. It includes a support platform, a rotating plate, a slider, and a mounting shell. A first gear is provided on one side of the mounting block, and a second gear is provided at the output end of a second motor. Two sets of the limiting shell have internally fitted sponge layers, and two sets of the limiting shell also have internally fitted activated carbon plates. By incorporating the second motor, sponge layers, and activated carbon plates, the second motor drives the welding assembly to swing back and forth at the desired angle, effectively improving the convenience of welding electronic components. The sponge layers filter impurities in the gas or fumes, and the activated carbon plates filter odors from the gas, effectively reducing the pollution of the surrounding environment and the harm to workers caused by harmful substances in the gas.

[0004] Based on the aforementioned patents, the clamping mechanisms of some automatic welding machines are unable to stably clamp workpieces of different shapes. For welding scenarios involving irregularly shaped parts or curved surfaces, traditional fixed-angle clamps cannot accurately fit the workpiece, which can easily lead to problems such as insecure clamping or workpiece deformation. In addition, traditional welding machines mostly adopt a single-piece welding mode, and manual loading, unloading, and positioning of workpieces are required after welding, resulting in long equipment downtime and making it difficult to achieve continuous and assembly line operations. Therefore, this invention provides a multi-functional automatic welding machine and its usage method. Summary of the Invention

[0015] A method for using a multi-functional automatic welding machine includes the following steps:

[0016] Step 1: Place the metal workpiece to be welded on the installation platform, rotate the double-acting screw, and drive the movable plate and clamping plate to clamp the workpiece through the opening and closing assembly. Start the motor, test the rotation of the transmission gear driving the installation shaft seat, and check whether the sliding of the installation platform along the support ring is smooth to ensure that the equipment is operating normally.

[0017] Step 2: According to the welding position of the workpiece, start the first electric push rod and the second electric push rod, adjust the horizontal and vertical position of the welding gun, rotate the lead screw, adjust the angle of the clamping plate to match the workpiece through the push assembly, and then drive the locking assembly to fix the clamping plate by the third electric push rod.

[0019] Beneficial effects

[0020] This invention provides a multifunctional automatic welding machine and its usage method. Compared with the prior art, it has the following advantages:

[0021] Firstly, the transmission gear in this invention is driven by a motor. The mounting shaft rotates on the mounting base through the meshing of the gear block and the transmission gear. This causes the L-shaped rod fixed to the upper end face of the mounting shaft and the support block to rotate along the inner wall of the support ring. This causes the mounting platform at the top of the support block to rotate along the upper surface of the support ring. The mounting platform is used to fix the objects to be welded. The mounting platform is set into four groups. After the objects on one group of mounting platforms are welded, the mounting platform is rotated in time to fill in the other mounting platforms and process them in time. There is no need to wait for the welding of a single object before clamping and positioning the next object. This realizes continuous welding work, greatly improves welding efficiency, realizes the assembly line operation of welding work, and makes the welding process more orderly and efficient.

[0022] Secondly, when the angle of the movable rod changes, the clamping plate is pushed upwards, allowing the angle of the clamping plate to be adjusted on the connecting block via the connecting shaft. This angle adjustment, tailored to the workpiece being welded, allows the clamping plate to flexibly adjust its clamping angle according to different shapes and welding positions. Whether it's flat welding, inclined welding, or complex curved surface welding, it can tightly clamp the workpiece surface, greatly improving the welding machine's adaptability to diverse welding tasks. It ensures the clamping plate matches the workpiece's unique contour, filling the gap in traditional clamping methods for handling irregularly shaped parts. This guarantees stable clamping of various complex-shaped workpieces, providing a guarantee for high-quality welding.

[0023] Thirdly, the dust collection system of the present invention, consisting of the outer casing, the dust collection casing, and the mesh frame, can collect the dust and spatter generated during the welding process in a timely manner, reduce the concentration of harmful dust in the workshop, improve the working environment, protect the health of operators, and reduce the risk of occupational diseases. The mesh frame at the suction port of the dust collection casing can intercept larger spatter and prevent them from entering the dust collection pipe and causing blockage, while ensuring that air and fine dust can pass through smoothly and be sucked in.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 The present invention provides a technical solution

[0035] A multi-functional automatic welding machine includes a mounting base 1, on which a mounting mechanism for automatic welding processing is provided. The mounting mechanism includes:

[0036] The adjustment assembly includes an L-shaped rod 4 connected by a gear assembly on the upper surface of the mounting base 1. A support block 401 is fixed to the upper end of the L-shaped rod 4, and a mounting platform 7 is fixed to the top of the support block 401. The L-shaped rod 4 is configured as four sets.

[0037] The clamping assembly includes a movable plate 703 connected to the upper surface of the mounting platform 7 via an opening and closing assembly. The inner wall of the movable plate 703 is provided with a clamping plate 801 connected via a pushing assembly. A connecting block 8 is fixed to the inner wall of the movable plate 703. A connecting plate 9 is fixed to the front wall of the connecting block 8. A connecting shaft 901 is rotatably connected to the vertical direction of the connecting plate 9. The clamping plate 801 and the connecting shaft 901 are fixedly connected. A locking assembly for fixing is provided on the upper outer wall of the connecting shaft 901.

[0038] In a preferred embodiment, a mounting seat 3 is rotatably mounted on the upper end face of the gear assembly. A toothed block 301 is fixed to the outer wall of the mounting seat 3. An L-shaped rod 4 is fixedly connected to the upper end face of the mounting seat 3. A mounting bracket 302 is fixed to one side of the upper end face of the mounting base 1. A motor 303 is fixed to the inner wall of the mounting bracket 302. A transmission gear 304 is fixed to the output end of the motor 303. The transmission gear 304 is meshed with the toothed block 301. A support rod 2 is fixed to the edge of the mounting base 1. A support ring 201 is fixed to the upper end of the support rod 2. The mounting platform 7 is slidably connected to the upper end face of the support ring 201. The transmission gear 304 is driven by the motor 303. Then, the mounting seat 3 is mounted on the mounting base 1 through the meshing action of the toothed block 301 and the transmission gear 304. The welding machine rotates on the base 1, which in turn drives the L-shaped rod 4 fixed on the upper end face of the mounting shaft 3 and the support block 401 to rotate along the inner wall of the support ring 201. This causes the mounting platform 7 at the top of the support block 401 to rotate along the upper surface of the support ring 201. The mounting platform 7 is used to fix the objects to be welded. The mounting platforms 7 are set into four groups. After the objects on one group of mounting platforms 7 are welded, the mounting platform 7 is rotated in time to fill in the other mounting platforms 7. Processing is carried out in time, without waiting for the welding of a single object to be completed before clamping and positioning the next object. This realizes the continuous operation of welding work, greatly improves welding efficiency, realizes the assembly line operation of welding work, and makes the welding process more orderly and efficient.

[0039] In a preferred embodiment, a mounting rod 5 is fixed at the center of the upper surface of the mounting base 1. A U-shaped bracket 501 is fixed to the upper end of the mounting rod 5. A support column 502 is fixed to the upper end of the U-shaped bracket 501. A slide rail bracket 503 is fixed to the top of the support column 502. A first electric push rod 504 is fixed inside the slide rail bracket 503. A slider 505 is fixed to the telescopic end of the first electric push rod 504. The slider 505 is slidably connected to the slide rail bracket 503. A second electric push rod 506 is fixed vertically to the slider 505. A welding gun 507 is fixed to the telescopic end of the second electric push rod 506. A collection shell 6 is fixed inside the U-shaped bracket 501. A dust collection shell 601 connected to the side wall of the collection shell 6 via a conduit is fixed to the side wall of the collection shell 6. A mesh frame 602 is fixed at the suction port of the welding gun 507. The mounting base 1 provides a stable support foundation for the entire equipment. The mounting rod 5, installed at the center of the upper surface of the mounting base 1, connects the U-shaped bracket 501, support column 502, slide rail bracket 503, and other components upwards in sequence to form the support structure of the welding gun 507. When the object to be welded is positioned on the mounting platform 7, the first electric push rod 504 is activated. The first electric push rod 504 extends and retracts, causing the slider 505, which is fixed to its extension end, to slide inside the slide rail bracket 503, thereby adjusting the position of the welding gun 507 in the horizontal direction to a suitable lateral position. After the position is adjusted, the second electric push rod 506 is activated. The second electric push rod 506 extends and retracts, causing the welding gun 507 to move in the vertical direction, so that... The welding gun 507 is accurately aimed at the area to be welded, ready to begin welding. During the welding process, welding fumes and spatter will spread in all directions. At this time, the collection shell 6 comes into play. Using the suction force generated by the dust suction shell 601 connected to the collection shell 6 through the conduit, the welding fumes and spatter are sucked into the collection shell 6. The mesh frame 602 at the suction port of the dust suction shell 601 can intercept larger spatter, preventing them from entering the dust suction pipe and causing blockage, while ensuring that air and fine dust can pass through and be sucked in smoothly. After the welding of a set of objects on the mounting platform 7 is completed, the transmission gear 304 rotates under the drive of the motor 303. Through the meshing of the tooth block 301 and the transmission gear 304, the mounting shaft 3 rotates on the mounting base 1, driving the L-shaped rod 4 and the support. Block 401 and mounting platform 7 rotate along support ring 201, moving the mounting platform 7 of the next set of objects to be welded to below welding gun 507. The above steps are repeated to continue welding. The fume collection system, composed of collection shell 6, dust extraction shell 601, and mesh frame 602, can promptly collect fumes and spatter generated during welding, reducing the concentration of harmful fumes in the workshop, improving the working environment, protecting the health of operators, and reducing the risk of occupational diseases. After one set of objects is welded, the next set of objects to be welded can be quickly moved to the welding position, reducing equipment downtime, greatly improving welding efficiency, and increasing output per unit time. The dust extraction pump at the upper end of collection shell 6, used to generate negative pressure, is existing technology.I will not elaborate further.

[0040] In a preferred embodiment, the opening and closing assembly includes a slide groove 701 on the upper surface of the mounting platform 7. A bidirectional screw 702 is rotatably connected to the inside of the slide groove 701 in the horizontal direction. A movable plate 703 is slidably connected to the inner wall of the slide groove 701. The bidirectional screw 702 is threadedly connected to the movable plate 703. A pair of positioning grooves 704 are provided on the upper surface of the mounting platform 7. The movable plate 703 is slidably connected to the mounting platform 7 through the positioning grooves 704. By rotating the bidirectional screw 702, the two sets of movable plates 703 are driven to open and close along the positioning grooves 704 on the mounting platform 7 through the bidirectional screw 702, thereby opening and closing the clamping plate 801 on the inner side of the movable plate 703 to clamp the object to be welded. Since the movable plate 703 can be opened and closed by rotating the bidirectional screw 702, the opening and closing assembly can adapt to welding objects of different sizes, and the operation is simple and intuitive.

[0041] In a preferred embodiment, the pushing assembly includes a movable groove 802 formed in the inner wall of the movable plate 703. A lead screw 803 is rotatably connected inside the movable groove 802. A movable block 804 is slidably connected to the inner wall of the movable groove 802. The movable block 804 is threadedly connected to the lead screw 803. A movable rod 805 is rotatably connected to the side wall of the movable block 804 via a rotating shaft. The end of the movable rod 805 is rotatably connected to the clamping plate 801 via a rotating shaft. The locking assembly includes a locking block 902 fixed to the outer wall of the connecting shaft 901. Locking holes 903 are evenly formed on the outer wall of the locking block 902. A first locking hole 903 is fixed inside the connecting block 8. The third electric push rod 904 has a locking plate 905 fixed to its telescopic end. A locking rod 906, which engages with a locking hole 903, is fixed to the inner wall of the locking plate 905. A clamping plate 801 is provided to clamp and fix the object. Then, by rotating the lead screw 803, the movable block 804 slides along the movable groove 802 on the inner wall of the movable plate 703 via the lead screw 803. The clamping plate 801 rotates with the movable plate 703 via the rotating shafts at both ends of the movable rod 805. When the angle of the movable rod 805 changes, it pushes the clamping plate 801, allowing the clamping plate 801 to move through the connecting shaft 9. 01. The angle of the connecting block 8 is adjusted according to the object being welded, allowing the clamping plate 801 to flexibly adjust its clamping angle according to different shapes and welding positions. Whether it is flat welding, inclined welding, or complex curved surface welding, it can tightly clamp the surface of the workpiece, greatly improving the welding machine's adaptability to diverse welding tasks. This allows the clamping plate 801 to match the special contour of the workpiece, filling the gap in traditional clamping methods when handling irregularly shaped parts. It ensures that workpieces of various complex shapes can be stably clamped, providing a guarantee for high-quality welding. Furthermore, the clamping plate 801 is connected to the connecting shaft 901. After rotational adjustment on the connecting block 8, the third electric push rod 904 located inside the connecting block 8 drives the locking plate 905 and the locking rod 906 on the inner wall to engage with the locking block 902 on the outer wall of the connecting shaft 901 and the evenly distributed locking holes 903 inside, thereby fixing the connected shaft 901 after rotational adjustment, ensuring the stability of the clamping plate 801, providing a strong and stable locking force, firmly fixing the connecting shaft 901, preventing the clamping plate 801 from shifting at an angle due to factors such as vibration and arc force during the welding process, ensuring that the workpiece always maintains a fixed posture throughout the welding process, and effectively improving the welding quality and consistency.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] A method for using a multi-functional automatic welding machine includes the following steps:

[0044] Step 1: Place the workpiece to be welded on the mounting platform 7. Rotate the bidirectional screw 702, which drives the movable plate 703 to clamp the workpiece with the clamping plate 801 through the opening and closing assembly. Start the motor 303 and test the rotation of the transmission gear 304 driving the mounting shaft 3. Check whether the sliding of the mounting platform 7 along the support ring 201 is smooth to ensure normal equipment operation. Specifically, by rotating the bidirectional screw 702, the two sets of movable plates 703 are driven to open and close along the positioning groove 704 on the mounting platform 7 through the bidirectional screw 702, thereby clamping the movable plate 703. The inner clamping plate 801 opens and closes to clamp the object to be welded. Then, by rotating the lead screw 803, the movable block 804 slides along the movable groove 802 on the inner wall of the movable plate 703 via the lead screw 803. Then, the clamping plate 801 rotates with the movable plate 703 via the rotating shafts at both ends of the movable rod 805. When the angle of the movable rod 805 changes, it pushes the clamping plate 801, so that the angle of the clamping plate 801 can be adjusted on the connecting block 8 via the connecting shaft 901, and the angle can be adjusted according to the object to be welded.

[0045] Step 2: Based on the workpiece welding position, activate the first electric push rod 504 and the second electric push rod 506 to adjust the horizontal and vertical positions of the welding gun 507. Rotate the lead screw 803 to adjust the angle of the clamping plate 801 to match the workpiece via the push assembly. Then, the third electric push rod 904 drives the locking assembly to fix the clamping plate 801. Specifically, activate the first electric push rod 504, which extends and retracts, causing the slider 505 fixed to its extension end to slide inside the slide rail bracket 503. This adjusts the position of the welding gun 507 in the horizontal direction, placing it in a suitable lateral position. Once in position, activate the second electric push rod 506. The second electric push rod 506 extends and retracts, driving the welding gun 507 to move vertically, so that the welding gun 507 is accurately aligned with the part to be welded, ready to carry out the welding work. During the welding process, the welding fumes and spatter generated will spread in all directions. At this time, the collection shell 6 plays a role. Using the suction force generated by the dust suction shell 601 connected to the collection shell 6 through the conduit, the welding fumes and spatter generated are sucked into the collection shell 6. The mesh frame 602 at the suction port of the dust suction shell 601 can intercept larger spatters and prevent them from entering the dust suction pipe and causing blockage.

[0046] Step 3: Finally, after a set of workpieces is welded, the motor 303 drives the transmission gear 304, which in turn drives the mounting shaft 3 to rotate via the toothed block 301. This rotates the mounting platform 7 of the next set of workpieces to be welded to a position below the welding gun 507. Specifically, the transmission gear 304 is driven by the motor 303, and the mounting shaft 3 rotates on the mounting base 1 through the meshing action of the toothed block 301 and the transmission gear 304. This causes the L-shaped rod 4 fixed to the upper end face of the mounting shaft 3 and the support block 401 to fit along the inner wall of the support ring 201. The rotation causes the mounting platform 7 at the top of the support block 401 to rotate along the upper surface of the support ring 201. The mounting platform 7 is used to fix the objects to be welded. Then, the mounting platforms 7 are set into four groups. After the objects on one group of mounting platforms 7 are welded, the mounting platform 7 is rotated in time to fill in the other mounting platforms 7 and process them in time. There is no need to wait for the welding of a single object to be completed before clamping and positioning the next object. This realizes the continuous operation of welding work, greatly improves welding efficiency, and realizes the assembly line operation of welding work.

[0047] During operation, firstly, by rotating the bidirectional screw 702, two sets of movable plates 703 are driven to open and close along the positioning groove 704 on the mounting platform 7 via the bidirectional screw 702, thereby opening and closing the clamping plate 801 on the inner side of the movable plate 703 to clamp the object to be welded. Then, by rotating the lead screw 803, the movable block 804 slides along the movable groove 802 on the inner wall of the movable plate 703 via the lead screw 803. Then, the clamping plate 801 rotates with the movable plate 703 via the rotating shafts at both ends of the movable rod 805. When the angle of the movable rod 805 changes, it pushes the clamping plate 801, allowing the angle of the clamping plate 801 to be adjusted on the connecting block 8 via the connecting shaft 901, and the angle is adjusted according to the object to be welded.

[0048] Then, the object to be welded is positioned on the mounting platform 7. The first electric push rod 504 is activated, and the first electric push rod 504 extends and retracts, causing the slider 505 fixed to its extension end to slide inside the slide rail bracket 503. This adjusts the position of the welding gun 507 in the horizontal direction, placing it in a suitable lateral position. After the position is adjusted, the second electric push rod 506 is activated, and the second electric push rod 506 extends and retracts, causing the welding gun 507 to move in the vertical direction, so that the welding gun 507 is accurately aligned with the part to be welded, ready to perform welding work. During the welding process, the welding fumes and spatter generated will spread in all directions. At this time, the collection shell 6 plays a role. The suction generated by the dust suction shell 601 connected to the collection shell 6 through the conduit is used to suck the welding fumes and spatter into the collection shell 6. The mesh frame 602 at the suction port of the dust suction shell 601 can intercept larger spatter to prevent them from entering the dust suction pipe and causing blockage, while ensuring that air and fine dust can pass through smoothly and be sucked in.

[0049] Finally, the transmission gear 304 is driven by the motor 303. The mounting shaft 3 rotates on the mounting base 1 through the meshing of the gear block 301 and the transmission gear 304. This causes the L-shaped rod 4 fixed on the upper end face of the mounting shaft 3 and the support block 401 to rotate along the inner wall of the support ring 201. This causes the mounting platform 7 at the top of the support block 401 to rotate along the upper surface of the support ring 201. The mounting platform 7 is used to fix the objects to be welded. The mounting platforms 7 are set into four groups. After the objects on one group of mounting platforms 7 are welded, the mounting platform 7 is rotated in time to fill in the other mounting platforms 7 for timely processing. There is no need to wait for the welding of a single object before clamping and positioning the next object.
